The Lowdown
Right, let’s have a look at what’s on the cards for Jaconé over the next couple of weeks.
There’s a bit of a slow start, but once we hit Monday the 14th, things start to look up. The first solid option pops up Friday afternoon the 11th with a 4ft S swell, period a nice 13 seconds and a gentle offshore breeze from the NE. That’s clean, with a moderate combined energy of 563 – feels like a good warm-up wave.
The real standout, and I mean the one you mark on the calendar, is Monday the 14th. Morning session sees a 5ft SSE swell, 9-second period, with a clean ENE offshore breeze. The energy is pushing 579 – proper push behind it. That afternoon holds up too, with a 5ft S swell and still offshore from the NE, energy even higher at 613. This is the pick of the week. Water temp is sitting at a comfortable 72°, about average for this time of year, so no surprises there.
Things go a bit lumpy through the middle of the week with onshores and chop, so give that a miss.
Friday the 18th morning is worth a look: 4ft S swell, 11-second period, stiff ENE offshore wind at 15 mph. It’s clean, but that wind is breezy – still rideable for the keen ones.
Now, keep an eye on Saturday the 26th. That’s a week and a half away, so treat it as promising but not locked in. The morning shows a solid 7ft SSW swell, with a 9-second period and a clean cross-off breeze from the ENE. Combined energy jumps to 1312 – that’s strong. By the afternoon it’s pushing 8ft S/SSW swell, 13-second period, and energy over 2000. This is for experienced surfers only – big, powerful, and heading towards expert territory. If the winds hold, that could be a serious session.
Crowds at Jaconé can show up sometimes, so don’t expect it empty, but with a bit of luck you’ll find your share.
Stay salty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
